It refers to pain upon ''removal'' of pressure rather than ''application'' of pressure to the abdomen. (The latter is referred to simply as ''abdominal tenderness''.) It represents aggravation of the [[parietal]] layer of [[peritoneum]] by stretching or moving. Rebound is regarded as one of the classic local signs of [[peritonitis]] which differentiates it from diseases such as [[appendicitis]]. The others are tenderness and guarding. However, in recent years the value of rebound tenderness has been questioned, since it may not add any diagnostic value beyond the observation that the patient has severe tenderness. ==See also== *[[Abdominal exam]] *[[Blumberg sign]] [[Category:Medical signs]]
